摘　　要：为系统研究建设项目可能对区域地下水环境造成的影响,结合场址区水文地质条件特征,建立基于包气带污染物迁移模拟的数值模型方法。根据污染物的迁移途径,对正常工况和非正常工况下污染物影响范围及距离、污染物浓度动态变化进行预测分析。影响预测表明污染物在地下水含水层中向各个方向均有运移,但主要以水平运移为主,污染物的迁移影响范围较小,对居民生活影响较弱。研究成果可为制定地下水污染的对策提供科学依据,研究方法可为同类工程提供借鉴。In order to systematically study the possible impact of construction projects on the regional groundwater environ⁃ment,combined with the characteristics of the hydrogeological conditions of the site a numerical model was established based on the simulation of the pollutant migration in the vadose zone.According to the migration path of pollutants,the influence range and distance,dynamic change of pollutants concentration under normal and abnormal working conditions were predicted and analyzed.The impact prediction shows that pollutants migrate in all directions of groundwater aquifer,but mainly horizontally.The migration of pollutants has a small range of influence and has a weak impact on the lives of residents.The research results can provide a scientific basis for formulating groundwater pollution countermeasures,and the research methods can provide ref⁃erence for similar projects.
